. this specification.

, My invention relates to an improvement in combined grain scourer,drier, and cooler; and it consists in,'first, the combination of ahotair pipe with branch pipes which extend around the body-or frame, andthrough which body or frame are made perforations to admit the heatedair to the grain; second, the combination of the perforated inclosingbody or I frame with the cones and funnels which are arranged therein,and the steam-pipes, the

' perforations through the inclosing-frame being made j ust'und'er thetops of the funnels;

third, the combination of the revolving cones, the funnels, the'blower,and the pipes which conduct the cold air into the inclosing-frame,

so as to cool the grain; fourth, in the arrangement and combination ofparts,which will be more fully described hereinafter.

The object of my invention is to combine a grain scourer, drier, andcooler in a single machine, so that damp and musty grain can be passedin at the top of the machine, dried,

scoured, and then cooled, so, as to be ready for shipment or storage.

'Figure 1 is a vertical-longitudinal section of "a machine embodying myinvention. Fig.

2 is a horizontal section taken through the,

grain-drier, Fig. 3 is a similar view taken through the cooler.

' A represents the body or frame of the grain- A drier, and B the bodyor frame of the grain- Yso cooler, the two being connected directlytogether by the .pipe-O,which is provided with a cut-off valve, D, so asto regulate the flow of the grain from the drier into the cooler.

Passing through the side of the lower portion of the grain-drier A isthe hot-air pipe E, which may lead from the furnace and hotair chamber,or from any suitable source from which acurrent or draft of hot air maybe obtained.- In this pipe, outside of the graindrier A, is placed asuitable valve, so as tov regulate the sfiction of the fan, which is connected with its upper end. This pipe E extends up through the center ofthe grain-drier to its top, and through which top it passes outward,where'it is connected to a suctionfan. This pipe is perforated inside ofthe grain-drier, so that the fan can draw away all of the moist aircontained in the grain-drier as fast as it is formed from the damp grainwhich is passing through the body or frame A. Upon thiscentralperforated pipe,E,are placed any suitable number of cones, F, andarranged in the frameat any suitable distance below these cones are thefunnels G, the-cones and funnels serving to alternately spread and thengather the falling grain in such a manner that the rising currents ofhot air will actupon the grain to the very best advantage.

Rising from the hot-air pipe, outside of the frame. or cylinder A, is avertical pipe, G, which connects with the pipe E outside of the valve ordamper, and which pipe G is connected with the flat pipes H, whichextend around the body or cylinder A horizontally just over the seriesof perforations through which the hot air which is introduced into theflat pipes passes. The hot air as -it passes into the frame A acts uponthe falling grain for the purpose of drying it. All of that hot moistair which rises up under the funnels passes out through the perforationsJ, which are made 'through'the frame A just below the. top edges of thefunnels. All of that hot moist air which rises up under the conessteam-pipes. Thesteam maybetaken directly from the boiler or any othersource that may be preferred. Th heat from these steam-pipes serves toheat the interior. of the grain-drier, in addition to the hot air whichis drawn in through the flat pipes H, and't'hus the damp,

moist grain which is passing through the body or cylinder A is subjectedto heat which is sufiicientlyintensc to thoroughly dry the grain beforeit escapes from the drier.

In the top of the body or cylinder A is placed a suitable damper, M, bymeans of which the escape of the heated air from the cylinder may beregulated. As the grain passes through the spout 0 it drops alternatelyfrom the cones to the funnels and from the funnels back to thecones,-being scoured by frictional contact with the parts with which thegrain comes in contact, and at the same time being heated sufficientlyto drive off all moisture. The grain after reaching the bottom of thedrier may be retained any length of time by the valve D, which controlsthe flow from the drier into the cooler.

In the cooler is placed arevolving vertical shaft, which carries theperforated cones O,

- which have the wings 1 formed upon their tops,

for the purpose of throwing the grain outward and around when the conesare made to revolve. Under these cones are placed the perforated funnelsQ, which serve to catch the grain as it falls from the cones in theusual manner. These cones and funnels are made of perforated material,so that the air which is forced into the cooler by the fan R will passup through the parts and act directly upon the grain as it is falling.

The blower 1%, for driving currents of cold air into the cooler,'hasconnected to it the pipe S, which .extends around the cooler, and has anumber of branch pipes, T, projecting 'up- Ward from it along the sidesof the cooler. These pipesT extend upward and pass through the sides ofthe cooler, and terminate in nozzles U inside of the cooler, just underthe funnels. These nozzles serve to direct the cold air in an upwarddirection, so as to act upon the falling grain so as to thoroughly coolit. Also under all of the funnels, or under the lower ones only, areplaced perforated circular pipes V, through which currents of air areforced upward through the cones, so as to act directly upon the grainwhile it is passing down over them. These circular perforated pipes areconnected to the pipes W, which also extend up from the pipe S.

Through the top of the cooler B are made suitable perforations, X,through which the currents of air can freely escape. As the grain fallsback and forth from the cones to the funnels it is subjected to blastsof cold air, and all of the dust and dirt is blown away through theseopenings in the top of the cooler. By the time the grain reaches the bo-tom of the cooler it is cleaned, ready to be shipped or stored in bins.

Having thus. described my invention, I claiml. The combination of theinclosing-frame, the hot-air pipe, the air-pipes which lead therefromand extend around the frame, the cones.

and the funnels, the frame being perforated both to admit the hot airfrom the pipes and to allow the damp hot air to escape, substantially asshown. 4

2. The combination of the body of the heater, the cones, the funnels,and the perforated central'pipe having a suction-fan connected to itsupper end with the steam-pipes and the pipes for forcing the hot airinto the frames, substantially as described.

3. The combination of the perforated cones and funnels with the blower,the air-pipes connected thereto, and the nozzles through which theblasts of cold air are discharged under the funnels, substantially asspecified.

4. The combination of the revolving perforated cones, the blower, thepipes connected thereto, and the circular perforated pipes which areplaced under the cones, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.-
